摘　　要：“惯用手段的直接置换”作为新颖性判断中常见情形之一,通常用于以抵触申请评价待审申请的新颖性,其目的在于避免与在先申请相比仅仅存在简单技术特征替换,技术方案仅发生了无关紧要的非实质性变化的在后申请被授予专利权,落实禁止重复授权原则和先申请制。正确适用惯用手段的直接置换通常需要考虑如下因素:存在置换的基础,两种技术手段的功能和作用相同,两种技术手段都是所属技术领域解决相同技术问题“惯用”的技术手段,两种技术手段的置换能“直接”进行。本文结合案例分析惯用手段的直接置换的适用。As one of the common cases of novelty judgment,"direct substitution of customary means"is usually used to judge whether a patent application possesses novelty relative to confl icting applicaitons.The purpose of doing this is to avoid a patent application being granted patent right just because of that the patent application involves simple replacement of technical featrues,and the replacement leads to non-substantive changes of minor importance in the technical solution on the basis of an earlier patent application which is filed prior to the filing date of the present application,and published or announced subsequent to the filing date.It is a crucial measure for implementing the principle of prohibition of double patenting and fi rst-to-fi le.In order to apply"direct substitution of customary means"correctly,the following factors should be considered:there is a basis of substitution of technical means;both technical means have the same function and eff ect;both technical means are customary technical means to solute the same technical problem in the technical fi eld which the application belongs to;the substitution of the two technical means can be made derectly.Application of the"direct substitution of customary means"is analyzed combining with a case.
